Subject: [PATCH 1/6] fix: coordinated graceful shutdown system to server

Introduces a new signal_handler module providing ShutdownSignal and ShutdownCoordinator for managing graceful shutdown across threads. Refactors main entry point, tray, and web modules to support coordinated shutdown using these primitives. Adds async and sync thread registration, monitoring, and timeout-based forced exit. Includes comprehensive unit and integration tests for shutdown coordination and signal handling.

Subject: [PATCH 4/6] Refactor ShutdownCoordinator to allow custom exit
 function

Replaces the FORCE_EXIT_DISABLED static and related methods with a configurable exit function in ShutdownCoordinator. This enables tests to inject a no-op or custom exit handler, improving testability and removing Windows-specific test logic. Updates all relevant tests to use the new constructor with a mock exit function.
